You can also start at <a href="http://en.wikipedia.org/wiki/Rete_algorithm">http://en.wikipedia.org/wiki/Rete_algorithm</a> and take it from there. It's not necessarily Drools pure, but it'll give you a good idea how such algorithms work.<br>

<p class="MsoNormal"><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Have been reading about how Rete operates and how Drools implements
Rete and so on .. and that Rete builds a network of nodes and each node is a
pattern and has memory of facts which satisfy the pattern …. just as a curiosity,
how does this all work internally ? what does it mean when they say that it
builds a network .. and nodes are shared and attached .. what does really
happen internally ? </span></font></p>
